Fresh water is more important than electricity.
Good businessmen will not pollute fresh water because economic growth is impossible without fresh water.
But we are destroying sources of fresh water, i.e forests and aquifers.

The amount of fresh water itself does not reduce because rain will bring water back to land.
However there will be insufficient water to use due to the following factors.

There is no forest to catch rainwater so rainwater flows back to sea as flood.

Water on land is polluted.

Usage of water is faster than suppy and conservation.

Countries that conserve fresh water will rise in power if major water crisis happens.
Israel is already doing that, turning desert to farmland.

Indeed the water that we save diligently has been lavishly wasted by many people.
But we still should continue to save water, while spreading the awareness.
